FRUIT-JUICE EXTRACTOR.

Application filed July 31, 1917. y Seria1No.-183,7f31.

To all whom it may concern.' j

Be it known that I, CHARLES B. BLcssINe, a citizen of the United States, and a resident of the city of Oakland, county of Alameda, State of California, have invented an Improvement in Fruit-Juice -EXtIaCtors5 and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will 'enable `others skllled in the art to which 'it appertains'to make and use the same. y Mylinven'tion relates to a fruit juice eX- tractor, and itis especially ladapted for use in lthe extraction'of the juices 0f citrus fruits; anditconsists inthe novel arrangement and4 construction of parts hereinafter described. f l

The object of my invention is to provide an easily-operated power-driven extractor of this type, capable of being driven at high speed, and one in which is combined 'efliu ciency, simplicity and cleanliness.

In order that my invention may be clearly understood and readily carried into effect, the same is described with reference to the accompanying drawings, in which similar numerals indicate like parts Figure 1 is an exterior view of my extractor.

Fig.' 2 is a verticalsectional view of the same.

Fig. 3 is a plan view of the same.

Fig. 4 is a horizontal section of Fig. 2,

taken on the line 4-4.

Fig. 5 is an enlarged view of the bulb carried by the rotary member.

In detail, my constructlon consists of a base, 2, to which is axed a frame oomprised of top and bottom cross-portions, 3 and 4, respectively, *tied together with slightly tapering standards, 5. Atthe center of the lower cross-portion, 4, is a suitable boss, 6, providedl with abushing, 7,

which constitutesabearing for the slightly reduced lower end of tf he rotatable shaft, 8. At the center of the top cross-portion, 3, is a boss-bearing, 9, for the said shaft, 8.. Surrounding the said standards, 5, and suitably attached thereto is a casing, 10. On the bottom cross-portion oftheJ said frame is an extended base, 11, upon which I mount a suitable electric motor, 12, by means of which the extractor is operated. Current is supplied to the said motor through the wire, 36, connecting with any suitable power source.

A circular cover, 13, is provided with a downwardly projecting circular flange, 14, which fits snugly within the extended portion of the casing, 10, and rests upon the top crossportion, 3. The upper Side of the base of thesaid cover is available as and constitutes a slightly outwardly inclined shelf, 15, for the fruit. The rim, 16, of the said Shelf is'turned lup to preventr the escape of any juice which may exude from cut fruitplaced on the shelf.` Integral with the base of the said cover and* rising from the central portion` thereof is a circular hollow bowl, 17, open .at the topand adapted to receive the removable guard, 18.` The center portion of the said cover has an upwardly projecting boss, 19, provided with an openingtherein slightly larger than the diameter of the rotatable shaft, 8, which extends therethrough. Inside of the bowl and resting on the inner sides thereof is a Screen, 20, which rests upon and surrounds the said boss, 19, a suitable distance below the top thereof. Entering the bowl, 17, through a suitable opening therein is an outwardly inclined dischargechannel, 21, which constitutes a spill-way for the extracted juice. The walls of the discharge-channel nearest the rim, 16, are cut away, as at 22 and 23, to permit the escape of any juice which may have exuded from cut fruit placed on the shelf to How into the said discharge-channel.

The rotatable shaft, 8, is threaded at its upper end to receive the extracting bulb, 24. This bulb is provided with a circular flange, 2,5, which projects downward a distance to enable it to surround that portion of the said boss, 19, which projects above the screen, 20. When the extractoris being 0perated the upwardly projecting boss, 19, and the downwardly projecting flange, 25, prevent any of the extracted juice from entering the opening of the shaft, 8, and consequently there is `no loss of juice. The bulb, 24, has downwardly curved rib-portions, 26, which aid in the extraction of the juice. A collar, 27, secured to the shaft, 8, prevents any vertical movement of the shaft. 'Suitably fastened to the shaft, 8, is a gear, 28, meshing with a gear, 29, secured to the shaft of the motor, 12, which comprises the operating mechanism for rotating the said shaft, 8, which carries the extractor-bulb, 24. As the said bulb is screwed on the shaft, 8, in a direction opposite to the direction of the rotations of the said shaft, the bulb will -exuding fruit juice,

not unscrew when the extractor is in operation.

By means of a rod, 30, adapted to engage an opening, 31, in the shaft, 8, the said "shaft may be held stationary when the bulb, 24 is bein screwed either. on or od the sai shaft. he rod, 30, extends through suitable openings cut in the casing, 10, and the boss 9, and it is supported at each end by said casing and boss. A coiled spring, 32, encircling the said rod and compressed between the boss, 9, and a collar, 33, secured to the said rod keeps the latter when not in use out of engagement with the said shaft, 8. A stop, 35, suitably secured to the rod holds the same in its proper position against the action of the spring. The rod is also provided at its outer end with a push-button, 34. My extractor is operated as follows: The operator starts the motor which causes the shaft carrying the ribbed-bulb to rotate. Cut fruit is then held against the bulb. The thrown against the inner surfaces of the bowl by the action of the revolving bulb, runs down the sides of the bowl and flows through the dischargechannel into any suitable container. r[he .screen prevents any dislodged fruit pulp To cleanse commingling with the fruit juice. the extractor after use, the rod, 30, is inserted in the opening, 31, in the shaft, 8, and the bulb unscrewed. The screen and cover may then be removed and cleansed with ease.

Having thus described my invention, what I desire to claim and to secure by Letters Patent, is:

l. In a machine of the character described, a. frame suitably affixed t0 a base, a casing for said frame, a cover for said frame and casing, the central portion of which rises to form a bowl, a boss projecting upward from the bottom central portion of said bowl, a rotary member journaled in said frame and extending upward ,through said boss within said bowl and carrying a removable ribbedbulb at its upper end, a downwardly proj ecting circular ange on said bulb encircling theupper portion of said boss within the bowl, a discharge-channel opening out of said bowl, a pulp screen within said bowl, and means for rotating said rotary member.

2. In a machine of the character described, a frame suitably aflixed to a base, a casing for said frame, a cover for said frame and casing, a bowl integral with and rising from the central portion of said cover, a boss projecting upward from the bottom of said bowl, a rotary member journaled in said frame extending upward through said boss with its upper end within said bowl and carrying a removable ribbed-bulb encircling .the upper portion of said boss,

al dischargechannel for said bowl, means for holding said rotary member stationary when said bulb is being placed thereon or removed therefrom, and means for rotating'said rotary member.

3. In a machine of the character described, a base, a frame allixed thereto, a casing for said frame, a cover for said frame and casing, the outer portion of said cover forming an outwardly declining shelf with upturned rim, a bowl integral with and rising` from the central portion of said cover and provided with a suitably seated detachable guard at its top portion, an upwardly projecting boss within the central lower portion of said bowl, a rotary member journaled in said frame with its upper end within the said bowl and carrying a removable ribbedbulb, the downwardly projecting circular flange of which surrounds the top portion of the said upwardly projecting boss, a discharge-channel entering said bowl, a pulpscreen within said bowl, and means for rotating said rotary member.

In witness whereof, Ihave hereunto set my hand at San Francisco, California this 25th day of July, A. D., 1917. 2
